Fifteen years ago, Hamato Yoshi and four baby turtles were mutated by ooze. During that time Yoshi, now known as Splinter, has trained the four turtles in the ways of ninja arts. Now the four have been tasked with defeating Hamato’s lifelong enemy, The Shredder. But along the way they find a young girl named April O’Neil, whose father was kidnapped by some ninjas along side other scientists across New York. The Turtles soon learn that the Shredder is partnered with an alien warlord named Krang to benefit one another.
